Which factors could influence oral temperature measurement? Select all that apply
1. Smoking
2. Eating or drinking
3. Exercise
4. Perfusion
5. Time of day
Correct Answer: 1,2,3,5
If the client has smoked a cigarette, the nurse should wait 15-30 minutes before measuring temperature because of the heat created in the oral cavity by the inhaled smoke. Eating or drinking will alter temperature readings, and the nurse should postpone temperature assessment 15-30 minutes after intake. The client who is exercising will have a slight elevation in temperature due to the heat produced by the muscles. Temperature readings have been shown to be lower in the morning than in the evening. Perfusion does not impact oral temperature readings, because the sublingual area is a very vascular area that is not greatly impacted by reduced peripheral perfusion.
